The gang is pretty excited. It is to be the trip of a lifetime - a trip on real cruicer! Even the thought of Georgie, their spoilt cousin, on the same boat could not dampen their excitement. While Georgie is busy wolfing down snacks by himself, they spend their time on jet-skis and looking for seashells on an unspoilt beach on an island. However, they could not help but notice a black boat in the background. It is not long before their adventure begins at sea, and ends on Penang Island where they get into a terrifying tussle with diamond smugglers, intent on grabbing back their precious hoard.
